Fix some bugs in the combined JS/CSS code (most of which I introduced

in my last refactor):

1) Actually combine the JS (I was only combining the CSS)
2) Add line breaks between the files and comment them so that we can
   find a specific file inside the blob.
3) Add an HTML comment to help developers figure out why they can't
   find their CSS/JS.
